Runkeeper v Garmin 310xt

A few days ago Michelle used the free Runkeeper app on her iphone and the Garmin for one of her runs. The results of the two were way out.

I sent an email to Neil in London as I know he’s tested every known techno gadget since the abacus about the discrepancy and he replied with:

” If it’s the 3G (which it is) she has no hope in built up areas or if you have a number of other apps running in the background”  The 4G apparently is more accurate.

This morning was my turn to use runkeeper as I was compelled to take the iphone as I had forgot to charge the Blackberry (I always take a phone just in case). Initially it had 2 drawbacks -1, The iphone is a lot bigger than the Blackberry and I had trouble getting into my pouch thingy. 2, I now had to run to her playlist – As it turned out it wasn’t too bad.

I put the Garmin on also to compare and started both up at 6:36am for a 6k run. It was near perfect weather for running; no wind and a comfortable 16C. I reckon I say that about every run – you have to love Melbourne don’t you? well I do!

The Runkeeper apps advises you of your pace in minutes per k, but as I neared the 900m mark it tells me that my pace is 5:35. Straight away I knew something was wrong; I was running much quicker and I hadn’t reached the 1k mark yet. It was dark so I didn’t check with the Garmin and was unsure whether the Runkeeper was set to tell me my pace every 5 minutes or every k. So I ran the next 5k worrying about how slow my pace was – 5:46, 5:55 etc and at one point 7:25, how debilitating.

I waited for the 6k buzz on the Garmin to end my run as I trust it and I can always use it as a barometer for all my runs. Garmin says – 31.37mins for 6k – Runkeeper 33:25 for 5.87k and I stopped it 50m or so after – had to close a couple of apps before stopping the activity!


I can understand the k’s being out, but the time? The calories burnt discrepancy is due to the app being set at 1kg in weight.

    I was just about to say exactly the same thing. How can the time be different?

    By the way, I rode past the “snake” I jumped over on our run the other day this morning, and I think it was just a shed skin, not a live snake. Still gave me a fright though!
